Application filed october 29, 1927. Serial No. 229,785.

This intention relates to improvements in holding frames for drawings and, the like, and has for one of its objects the provision of means for clainpingly holding a drawing and a superimposed sheet of tracing cloth thereon and to prevent any relative move ment between the said drawing and tracing cloth.

Another object of the invention is. to provide a structure of this nature, the support- 1 ing base of whiclrinay be made to assume an inclined position to the horizontal plane when a drawing and a superimposed sheet of tracing cloth is ciamped thereon.

A further object of the invention is to provide a device of this nature which is simple and inexpensive, and yet eflicient and substantial in construction.

()ther objects and advantages will appear the nature of the improvements is better understood, the invention consisting substantially in the novel arrangement and corclation of instrumentalitics herein fully described and illustrated in the accompany ing drawings,- wherein similar reference characters are used to describe corresponding parts throughout the several views, and then finally pointed out and specifically defined and indicated in the appended claims.

tration, is shown'in the accompanying draw-,

ings, in which Figure 1 is a perspective view ofmy iniprovedholding frame shown in closed or clamping position. l

Figure 2 is asectional view taken on line 22 Fig. 1. V

Figure 3 is a similar view to that shown t in F ig. 2, but with the parts shown in open position and Fig.4 is a fragmental top plan viewof the supporting base or table.

Referring now to the drawing in detail 5 indicates a frame hingedlv mounted on a base or table 6. :Thesaid base orutable 6 is preferablymade of .a. single sheet of metal The disclosure made the basis of exempli and the rear edge thereof isrolled overand entends laterally beyond the body, to form lnng'ePms'L-T which are inserted into corresponding openings in the rear upper portion of theframe oftli'e' said frame 5 being slightly sprung outwardly to permit of the above insertion. Thebody portion or the table 6 is providedwith depressions forming strengthening or stiffening ribs 8-8 which run substantially the entire length of the said table body. The said table is furc theriprovided at the front thereof with a depending wall 9 and a supporting section 10 terminating in a bead 11. f

r The frame 5 is provided with an opening 12 at the top wall 5 thereof and has a rear wall 1.3 of a height greater than the front wall 14 in order that thesaid top wall inclines downwardly from the rear to the front to conform to the inclination of the tablefi and to overlie same. Side walls 15 and 16 depend from the top wall '5. The frame 5 is also preferably made of a single sheet of metal and is providedat the bottom of the rear, front, and side walls thereof, with beads 17 through which passes a rectangular wire frame 18 to give rigidity to the frame, The head 17 on the front wall 14 in con-Y junction withthe bead'll on the table forms a locking means for locking in position a drawing 20 or the like and a superimposed sheet of tracing" cloth 91 betweenthe table top and the frame 5. The said drawing and sheet of tracing cloth are maintainedin lateral and longitudinal alinement' by the walls of the frame 5. l

The operation of the device is as follows? If it is desired to inserta drawing and a sheet of; tracing cloth into the holder, the

frame 5 is swung upwardly on its hinges 7 7 into the Fig; 3 position by holdingthe bead 11 downand pulling upwardly on a ring 23 provided for this purpose, the drawing and tracing clothare placed on the tabletop 6 even with the edges thereof and'the frame 5 is then swung downwardly until, the front bead 17 comes into locking engagement with the bead 11 on the base portion 10 The parts are then in position to permit the user totrace the drawing or the like without fear that the same or tracing cloth will'move relatively to each other.

From the foregoing it will be seen that I have provided a simple and efficient holding frame, for drawings, to securely hold therein a drawing and a sheet of tracing cloth superimposed thereon and to readily remove the said drawing and tracing when desired.

Having described my invention, what I claim as new and desire to secure by Letters Patent is r 1. In a drawing f'ame adapted to hold a plurality of sheets superimposed upon one anotheiya table, a hinge pin portion integral with the table at one end thereof, a wall depending froin the opposite end of the table and integral therewith, a base portion integral with and 'bent at an angle to the wall, a frame hingedly mounted on the table and provided with an opening in the top wall thereof, depending front. rear and side walls on the frame integral with the top wall, a bead on each of the depending walls, a reinforcing wire frame in the heads, and a head on the table hase coaeting with the head on the front wall of the frame to form locking means between the table and frame.

2. In a holding device for drawings, a frame, a downwardly sloping top wall on the frame having an openin therein. and a table beneath the top wal hingedly connected to the frame, said table being parallel to the top wall when in closed position and adapted to assume a horizontal position when the frame is swung upwardiy.
